Threat Source newsletter (April 20, 2023) — Preview of Cisco and Talos at RSA

Summary: The UK's National Cyber Security Center released a report on a sustained campaign by a Russian intelligence agency, dubbed "Jaguar Tooth," targeting a vulnerability in routers that Cisco patched in 2017. The newsletter also notes a 21-year-old was arrested for allegedly leaking sensitive Pentagon and Department of Defense documents and images on a Discord server, and that Montana is set to become the first U.S. state to ban TikTok downloads.

Why it matters: Talos states that attackers have been particularly successful against infrastructure running out-of-date software, and that the results range from unwitting participation in criminal activity to events of true national security impact.
